Utopianism is a supercilious term to describe serious, thoughtful conceptions of world-order, peace and human fulfilment.

Utopianism rejects the struggle of its existing social situation in favour of a world of its own making. Such subjectivity has no practical chance of devising proposals applicable to the world which exists.
